I'm trying to restore a 'vintage' iPad, Ist gen. I keep getting error messages 2001/2002....something to do with USB apparently. Any help would be gratefully received. Doug

Check your USB connections

If you see error 4005, 4013, or 4014, use these steps.

If you see one of the errors below, check your USB connection, USB cable, USB port, or computer:

• 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643–1650
• 2000, 2001, 2002, 2005, 2006, 2009
• An error that includes "invalid response"

Here's what to check. Try again after each step:

1. Use the USB cable that came with your device. If you don't have it, try a different Apple USB cable.
2. Switch to a different USB port on your computer. Don't plug into your keyboard.
3. Switch to a USB port on a different computer.
4. If you still see the error, check for other USB issues, check your third-party security software, then check your hardware.

If you still see an error, contact Apple Support.

My iPad 1 works fine. Sounds like the 30-pin port may need to be cleaned out, or it may have died. To try to clean it out, use a soft, clean toothbrush, and see if you can clean any dust, dirt, or other gunk out of the 30-pin port.

And when you indicate that there is nothing wrong with the USB port on the machine you are hooking up to, have you tried other cables, other ports on the computer?

Cheers,
